Fast Lattice-Free Keyword Filtering For Accelerated Spoken Term Detection

Collection:

IEEE ICASSP 2020 Virtual Conference May 2020

We present a novel set of keyword detection techniques to accelerate spoken term detection for known queries with minimal loss in accuracy. Using only ASR frame-level acoustic posteriors we can train multiple models to effectively detect non-target segmen
